Not a big issue sixty years ago. The immigrants he was thinking about were displaces refugees, many of them from countries taken over by the Communists. For one thing, the suppression of the Hungarian revolution had made the country much more open to changing the immigration laws. Hardly a left-wing initiative. As for Mexico, the Eisenhower administrative had worked out the bracero plan. In any case, looking back, I contend that the biggest reason for the immigration problem we have now is what I call the ZPG mentality which ended the baby-boom and has so greatly reduced the Euro-American population in this country.
Again, LOL.
Not a big issue? You think that JFK just wrote that book in 1958 for nothing, and that only a quick seven years later the most destructive legislation in American history was signed into law?
